javamail 发送验证邮件(jsp/servlet实例源码)发送email：包括文本邮件、html邮件、带附件的邮件、smtp验证接收email：pop3远程连接、收取不同mime的邮件、处理附件首先需要配置环境。需要mail.jar和activation.jar两个包。地址在上，很容易找到。放到classpath中，比如我的是这样.e:tomcat5commonlibactivation.jare:tomcat5commonlibmail.jare:tomcat5commonlibmailapi.jare:tomcat5commonlibe:jdk1.5libdt.jare:jdk1.5libtool.jare:jdk1.5libe:jdk1.5bine:jdk1.5。-例子一、javamail.jsp发送验证邮件源代码javamail电子邮件发送系统javamail电子邮件发送系统本例子是用javamail来发送邮件的最简单的例子，认证才能正常发送邮件。收件人email:发件人mail：邮件标题内容：stringtouser=request.getparameter(recipients)!=null?request.getparameter(recipients):out.print(recipients:+touser)stringfromuser=request.getparameter(frommail)!=null?request.getparameter(frommail):out.print(frommail:+fromuser)stringsubject=request.getparameter(subject)!=null?request.getparameter(subject):out.print(subject:+subject)stringcontents=request.getparameter(contents)!=null?request.getparameter(contents):out.print(contents:+contents)out.print()trypropertiesprops=newproperties()props.put(mail.smtp.authtrue)/是否验证props.put(mail.smtp.hosthost)props.put(mail.smtp.useruser)props.put(mail.smtp.passwordpassword)booleansessiondebug=falseauthenticatorauth=newauthenticator()/sessionmailsession=session.getdefaultinstance(propsauth)/有时可能被拒绝sessionmailsession=session.getinstance(propsauth)/用户验证/sessionmailsession=session.getinstance(props)mailsession.setdebug(sessiondebug)messagemsg=newmimemessage(mailsession)msg.setfrom(newinternetaddress(fromuser)msg.setrecipient(message.recipienttype.tonewinternetaddress(touser)msg.setsubject(邮件标题：+subject)/(mimemessage)msg).setsubject(subjectgbk)/设置中文标题msg.setsentdate(newdate()stringtext=javamail.jsp发送认证邮件测试。+contentsmsg.setcontent(textcontenttype)transporttransport=mailsession.gettransport(smtp)transport.connect(hostuserpassword)transport.send(msg)你的邮件已发送，请返回。-例子二、用servlet来发送邮件，postmail.java源代码ernet.importjava.util./创建日期2005-12-1todo要更改此生成的文件的模板，请转至窗口首选项java代码样式代码模板/authoradministratortodo要更改此生成的类型注释的模板，请转至窗口首选项java代码样式代码模板/publicclasspostmail/stringmailform=stringmailto=stringmailsubject=stringmailcontent=/stringhost=stringuser=usernamestringpassword=xxxxxpublicvoidsethost(stringhost)this.host=hostpublicvoidsetaccount(stringuserstringpassword)this.user=userthis.password=passwordpublicvoidsend(stringfromstringtostringsubjectstringcontent)propertiesprops=newproperties()props.put(mail.smtp.hosthost)/指定smtp服务器props.put(mail.smtp.authtrue)/指定是否需要smtp验证try/sessionmailsession=session.getdefaultinstance(props)/用这个有时被拒绝；sessionmailsession=session.getinstance(props)mailsession.setdebug(true)/是否在控制台显示debug信息messagemessage=newmimemessage(mailsession)message.setfrom(newinternetaddress(from)/发件人message.addrecipient(message.recipienttype.tonewinternetaddress(to)/收件人/message.setsubject(subject)(mimemessage)message).setsubject(subjectgbk)/得到中文标题forlinux，windows下不用/message.setsubject(subject)/邮件主题/内容类型content-type/普通文本为text/plainhtml格式为text/htmlmessage.setcontent(contenttext/htmlcharset=gbk)/message.settext(javamail，你好!)message.settext(content)/邮件内容message.savechanges()transporttransport=mailsession.gettransport(smtp)transport.connect(hostuserpassword)transport.sendmessage(messagemessage.getallrecipients()transport.close()catch(exceptione)system.out.println(e)publicstaticvoidmain(stringargs)/postmailsm=newpostmail()sm.sethost()/指定要使用的邮件服务器sm.setaccount(xxxxxxxxxx)/指定帐号和密码/paramstring发件人的地址paramstring收件人地址paramstring邮件标题paramstring邮件正文/调用postmail.java的jsp文件：postmail.jsp源代码电子邮件java.util.datedate=newjava.util.date()out.print(newjava.util.date()out.print()本例子是调用postmail.java来发送认证的邮件，需要下载mail.jar和activation.jar，并设置classpath请输入发件人电子邮件:请输入收件人电子邮件:0&!email.matches(w+(-+.w+)w+(-.w+).w+(-.w+)$)out.print(发件人邮件地址不正确)returnif(toemail.trim().length()0&!toemail.matches(w+(-+.w+)w+(-.w+).w+(-.w+)$)out.print(收件人邮件地址不正确)returnif(email.trim().length()0&toemail.trim().length()0)trymail.send(emailtoemailtestpostmail.java中文javamail，你好postmail!)out.print(邮件已发送)catch(exceptione)out.print(出错了)out.print(e.getmessage()system.out.print(e.getmessage()-其他java源代码：mailmanager.java源代码ernet.importjava.util.importjavax.activation.importjava.io.publicclassmailmanager/sun.misc.base64encoderenc=newsun.misc.base64encoder()/msg.setsubject(=?gb2312?b?+enc.encode(subject.getbytes()+?=)/比如说有一个邮件帐号:/pop3_host_name和smtp_host_name分别是这邮件地址的pop3和smtp服务器dns/则smtp_auth_user=smtpusersmtp_auth_pwd就是该帐号的密码privatefinalstringpop3_host_name=privatefinalstringsmtp_host_name=privatefinalstringsmtp_auth_user=usernameprivatefinalstringsmtp_auth_pwd=xxxxxxprivateauthenticatorauth=newauthenticator()publicpasswordauthenticationgetpasswordauthentication()returnnewpasswordauthentication(smtp_auth_usersmtp_auth_pwd)publicvoidsendmail(stringtoaddrstringsubjectstringbodystringfromaddrstringcontenttype)trypropertiesprops=newproperties()/指定smtp服务器，邮件通过它来投递props.put(mail.smtp.host(string)smtp_host_name)props.put(mail.smtp.auth(string)true)/sessionsession=session.getdefaultinstance(propsauth)sessionsession=session.getinstance(propsauth)/messagemsg=newmimemessage(session)/指定发信人msg.setfrom(newinternetaddress(fromaddr)/指定
